Przykładowy opis:

The photo shows two men on a narrow street next to a building. One is standing behind the building wall. He's wearing a jumper with a hood covering his face and looks on the street. The other man is walking and talking on a phone. He doesn't know about the first man.

I think the first man wants to steal the other man's phone and maybe even mug him and take his wallet too. I think so, because he doesn't want to be seen. He makes sure that there's no one else around and that his face isn't visible. He's definitely up to no good.
